Selection of inhibitor and depressor additive for oil of the Verhnechonsky oilfield

Authors: I.V. Prozorova, N.V. Yudina, N.A. Nebogina, Yu.V. Loskutova, G.I. Volkova (Institute of Petroleum Chemistry, Siberian Branch of RAS)

On an example of oil of the Verhnechonsky oilfield deposit formation in a range of temperatures of a stream of oil 50-10 °С and temperatures of deposit formation surfaces -30 … +30 °С is studied. For formation prevention of asphalt-resinparaffin deposit it is tested industrially let out 10 additives of depressor and inhibitor type. It is shown that efficiency of inhibitor additives depends on oil temperature. The maximum inhibitor and depressor effect in the field of negative temperatures of oil is reached with addition of an additive by SIM-DP.
